IIDIIIIFRO'V'IEIID MEANS PQR 'ATTACHING- COVERS TO GLASS J'VARS.

The Schedule referred to in these Letters Patent and making p art of the same.

To all whom it may concern:

Be it known that I, DANIEL C :RIPLrmof the city of Pittsburg, in the county ot' Allegheny, and State of ,Pennsylvania'have invented a new and useful 1m provement in Attaching Covers to Glass Jars; and I do hereby declare the following to be a full, clear, and

Iexact description thereof, reference being had to the accompanying drawing, making a part of my specilication, in which l V i Figure l is a side view of the glass body of' a sii-upjar or pitcher, illustrative of a part of my improvement';

Figure 2, by a like view, shows my improvement complete; and Y Figure 3` shows the oval form of the mouth of the neck, whichl sometimes use; i

Like letters of reference indicate like parts in each. The ordinary mode of attaching jar-covers to glass jars, is by a. plaster-of-Paris or other like cement,I introduced betweentheneck ofthe jar and the neck of the cover, a little room or space being left between the two for such purpose. This mode is'liable to the o^-jections that it is slow, dirty, andl requires va considerable length and size of neck, so as to give sufficient lap and room for a cement joint.

The nature of my invention. consists in .'tting the jar-cover of `a ewer-mouthed metallic-capped glass jar to the neck of .the jar, so as to go ou tightly, and at-` taching such covers to glass jars, pitchers, 86o., by

grooving or indentng'the neck of the cover into one or more grooves or part grooves, previously made in the neck of the jar, so as to secure a tight joint between them; also in making such glass jars with a such purpose; and also in the modes hereinafterdescribed ofxpreventing the turning of the jar-cover on the neckof the jar. 4

ToV enable others skilled in the art to make and use my invention, kI will proceed to describe its construction and manner'of use.

a represents the glass body of a Sirup-pitcher or jar,

made by being blown in. a mould.

In the neck of the mould are one or -more project- Ving rings, byjwhicb one or more grooves, a', are made in the outer face of the neck b of thejar, near its upper end.

Such groove or grooves a may extend entirely or only a part of the way around the neck of the jar;

but preferably Ilmake them extend entirely around,l

except at sonic one point, as at4 a projection, c, the

outer face'ot' which may be flush with the faceot' the.

smallerthau has heretofore been done, it being only4 Y necessary that it extend down or lapon tothe neck b of the jar suliciently far to cover the groove or grooves a.

The covers are madeof such size as to it on tightly and neatly..

' I then groove, or indent, or burnis'b the metal of the cap-neck e into the groove or grooves a', previously formed in the jar-neck b, as shown at ef. This may be done in any suitable machine, by fixing the vjar therein so that it will be rotated against a suitable preferably in the line of one of the grooves a. As the metal of the neck is then pressed down into the groove on either side of' it, the cap cannot be` turned or rotated thereon.

But I also accomplishthe same object by making' the jar-neck b slightly oval in form, that is, slightly elliptical in cross-section, as shown in iig. 3.

It' so desired, each groove a', -if there be more than one, may extend entirely around the jar-neck 71and the metal of the cover be burnished orindented therein, in the manner above set forth. V

lhe .advantages ot this mode of attaching covers arc, cbieliy, that the covers can be attached at least )four times as rapidly as by the ,old method; that itis groove, or grooves, or part grooves inthe neck for free from the dirt inseparably connected with the use of cement; and that by it a large saving `is elected in the quantity of metal required in the neck c of the cover, a short, closely-fitting neck answering equally Vas well as a long one, with'an open joint for cement.

VVitb vthe jar-cover so made as to fit tightly on to the glass body of the jar, other modes of tstening, besides that of indenting the metal of the coverint-o a groove in the body ot' the jar, may be adopted, it

only being necessary that the metal of the neck of Y the cover be brought into such close contact with au uneven' surface on the outside or inside of tbe neck of the jar, that a close- 'and rm union shall be sebetween the two by pressing the metal of the cover.

. into close Contact witirthe 3. An oval-mouthed glass jar, with grooved neck,

made substantially as described, and for the purposes set forth.

In testimony whereof, I, the said DANIEL O. RIP- LEY, have hereunto set myrhzmd.
